BIT.TRIP.BEAT Updated

Added "machine-based" options (ie mouse sensitivity, resolutions) into the config file for manual editing. Manual edits of config file are still allowed, but should not be needed. **Since editing the config file is not an in-game supported feature, it's possible that manual edits may be deleted when saving from the options menu. The options are:

"Fullscreen" : "yes", "no"

"Resolution" : fullscreen resolution, eg "1280x720"

"WindowSize" : size of the window when not in fullscreen, eg "1280x720"
